Prepared as a tribute to Donald A. Riley, the essays that appear here are representative of a research area that has loosely been classified as animal cognition -- a categorization that reflects a functionalist philosophy that was prevalent in Riley's laboratory and that many of his students absorbed. According to this philosophy, it is acceptable to hypothesize that an animal might engage in complex processing of information, as long as one can operationalize evidence for such a process and the hypothesis can be presented in the context of testable predictions that can differentiate it from other mechanisms. The contributions to this volume represent the three most important areas of research in animal cognition -- stimulus representation, memory processes, and perceptual processes -- although current research has considerably blurred these distinctions.

The Ecology of Wild Birds Diseases would present a new insight to infectious diseases from an ecological and epidemiological view. The book will help students, researchers, biologists, veterinarian and wildlife managers and conservationists to understand the complex epidemiological interactions among different factors, those that are important for occurrence and expansion of diseases; some which in turn can significantly impact other wild and domestic animal populations and human health. The purpose of the book is to serve as a reference text for understanding the complexity of diseases of wild birds bringing essential ecological and epidemiological information into one volume.

This book presents comprehensive information on various aspects of ecology with special reference to insects, to form a platform to design an ecologically sound insect pest management. Insects are the most dominant and diverse group of living organism on earth. Owing to their smaller size, smaller space and food requirements, more number of generation per unit time, insects serves as one of the best subject matter for studies on various ecological aspects such as chemical ecology, population dynamics, predator/parasitoid-prey interactions etc. The knowledge on various aspects of insect ecology helps in formulating an effective environmentally benign insect pest management. This book is of interest and use to the post graduate students and researchers working on various aspects of insect ecology with special emphasis on population dynamics, chemical ecology, tri tropic interactions, ecological engineering and Ecological Insect pest management.

The NATO Advanced Research Workshop on "Behavioural Adaptation to Intertidal Life" held in Castiglioncello, Italy (May, 1987) was attended by 50 participants, most of whom presented requested lectures. It was perhaps the first time that specialists of various animal groups, from cnidarians to birds, were able to meet and discuss the importance of behavioural adaptation to this peculiar, sometimes very harsh environment. But the taxonomic barrier is not the only one which the meeting attemped to over come. Lately, the research on intertidal biology has spread from pure taxonomy and static analysis of community structure to such dynamic aspects as intra- and interspecific relationships, and physiological mechanisms aimed at avoiding stress and exploitation of limited-resources. This increasing interest stems not only from an inclination for this particular ecological system and some of its typical inhabitants, but also from the realization that rocky and sandy shore communities are suitable models for testing and improving some global theories of evolutionary biology, behavioural ecology and sociobiology. The number of eco-physiological and eco-ethological problems emerging from the study of intertidal animals is fascinatingly large and a complete understanding of this environment cannot be reached using a strictly "reductionistic" or a pure "holistic" approach."

How can we engage communities? What is empowerment? To what extent should the project process be participatory? How is an outsider-insider relationship handled? How do researchers negotiate with the hegemony of western cultural interpretations? How are organizational and contextual influences handled in a project? What leadership demands do such projects place on researchers? What is capacity building? What are creative leaders and creative communities? How does the researcher journey from their studio to the situation? M(2) Models and Methodologies for Community Engagement discusses key theoretical constructs - community engagement, capacity building, and community empowerment - in order to demonstrate how theory and practice are relevant to the development of forms of community involvement. The book maps the attributes of community based projects by moving beyond simply bringing people together from a variety of disciplines, and taking an approach which is transdisciplinary and applicable across cultures and genres. Here, all people - including the community - are ongoing contributors, and can freely move between their own and others' discipline-specific arenas. M(2) differs from and extends on other works in this field of practice and research, in that its transdisciplinary, collaborative approach positions the community as a particular kind of discipline to create real change in diverse locations and fields of experience. The book is in itself a model of community engagement, as the researchers have formed a community of research and practice for change, and have developed a transformative model for community engagement that is greater than the sum of its parts - hence M(2). M(2) offers a valuable resource for students, researchers, academics, practitioners, policy developers and volunteers from the fields of architecture, interior architecture, health, planning, anthropology, education, home economics, communication, political studies and development studies.

Black-tailed and mule deer represent one of the largest distributions of mammals in North America and are symbols of the wide-open American West. Each chapter in the book was authored by the world's leading experts on that topic. Both editors, James R. Heffelfinger and Paul R. Krausman, are widely published in the popular and scientific press and recipients of the O. C. Wallmo Award, given every two years to a leading black-tailed and mule deer expert who has made significant contributions to the conservation of this species. In addition, Heffelfinger has chaired the Mule Deer Working Group sponsored by the Western Association of Fish and Wildlife Agencies for more than 15 years. This working group consists of the leading black-tailed and mule deer experts from each of 24 states, provinces, and territories in western North America, putting them at the forefront of all conservation and much of the research on this species. The book represents all current knowledge available on these deer, including how changing conditions such as fires, habitat alteration and loss, disease, climate change, socio-economic forces, energy development, and other aspects are influencing their distribution and abundance now and into the future. It takes a completely fresh look at all chapter topics. The revisions of distribution, taxonomy, evolution, behavior, and new and exciting work being done in deer nutrition, migration and movements, diseases, predation, and human dimensions are all assembled in this volume. This book will instantly become the foundation for the latest information and management strategies to be implemented on the ground by practitioners and to inform the public. Although this book is about deer, the topics discussed influence most terrestrial wildlife worldwide and the basic concepts in many of the chapters are applicable to other species.

Fish - including cyclostomes, elasmobranchs, and teleosts - display a wide variety of ways of coping with the stringent conditions they encounter in the aquatic environment. This diversity is especially evident in the female genital systems where some fish spawn profligate numbers of small eggs while others develop a few yolky eggs that may receive parental care. Parental care is carried to extremes in viviparity where eggs develop within the ovary or oviducts of the mother.This volume describes the myriad ways in which fish have approached problems of reproduction - it is an amply illustrated comparative study of the microscopic structure of the female genital systems of fish.

The importance of the Neotropics to the world's climate, biogeochemical cycling and biodiversity cannot be questioned. This book suggests that gradients are key to understanding both these issues and Neotropical ecosystem structure, function and dynamics in general. Those gradients are either spatial, temporal or spatio-temporal, where many temporal and spatio-temporal gradients are initiated by disturbances (e.g., tree-fall, landslide, cultivation). And in particular for the Neotropics, three large spatial gradients - latitude, longitude, altitude (elevation) - are of critical importance. The editor has over 30 years of experience investigating Neotropical gradients in Costa Rica, Puerto Rico, Peru and Ecuador, and has published 5 previous books on different aspects of the Neotropics. Once again he has assembled top-shelf Neotropical scientists and researchers, here to focus on gradients: their nature, interactions and how they structure ecosystems.

This monograph studies a series of mathematical models of the evolution of a population under mutation and selection. Its starting point is the quasispecies equation, a general non-linear equation which describes the mutation-selection equilibrium in Manfred Eigen's famous quasispecies model. A detailed analysis of this equation is given under the assumptions of finite genotype space, sharp peak landscape, and class-dependent fitness landscapes. Different probabilistic representation formulae are derived for its solution, involving classical combinatorial quantities like Stirling and Euler numbers. It is shown how quasispecies and error threshold phenomena emerge in finite population models, and full mathematical proofs are provided in the case of the Wright-Fisher model. Along the way, exact formulas are obtained for the quasispecies distribution in the long chain regime, on the sharp peak landscape and on class-dependent fitness landscapes. Finally, several other classical population models are analyzed, with a focus on their dynamical behavior and their links to the quasispecies equation. This book will be of interest to mathematicians and theoretical ecologists/biologists working with finite population models.

This book provides, for the first time, a comprehensive overview of the fundamental roles that ecological interactions play in extinction processes, bringing to light an underground of hidden pathways leading to the same dark place: biodiversity loss.We are in the midst of the sixth mass extinction. We see species declining and vanishing one after another. Poached rhinos, dolphins and whales slaughtered, pandas surviving only in captivity are strong emotional testimonials of what is happening. Yet, the main threat to natural communities may be overshadowed by the disappearance of large species, with most extinctions happening unnoticed and involving less eye-catching organisms, such as parasites and pollinators. Ecosystems hide countless, invisible wires connecting organisms in dense networks of ecological interactions. Through these networks, perturbations can propagate from one species to another, producing unpredictable effects. In worst case scenarios, the loss of one species might doom many others to extinction. Ecologists now consider such mechanisms as a fundamental - and still poorly understood - driver of the ongoing biodiversity crisis. Hidden Pathways to Extinction makes the invisible links connecting the fates of species and organisms evident, exploring why complexity can enhance ecosystem stability and yet accelerate species loss. Page after page, Strona provides convincing evidence that we are primarily responsible for the fall in biodiversity, that we are falling too, and that we need to redouble our conservation efforts now, or it won't be long before we hit the ground.

Bringing together recent advances in the research into the ecology and biology of brown and sea trouth, this book places them in their ecological setting and shows how an understanding of their biology and environment aids efficient management of both fish stocks and the surroundings. In particular, it concentrates on the management of the fish in natural flowing waters, and discusses issues such as how to determine an efficient feeding strategy and the influence of hatchery stocks upon wild populations. A detailed case study focusing on the French experience is of especial interest. Biology and Ecology of the Brown Sea Trout synthesizes the considerable body of research available and provides a significant tool for the better management and conservation of these important fish.

The first book on zoo/captive animal behavior and how this applies to welfare. Despite growing evidence of the need to implement more suitable, naturalistic practices into zoo animal welfare, it still seems to be somewhat overlooked - this book will address this oversight. Includes specific detail and examples focusing on taxa, a huge factor in managing animals in zoos that has not previously been addressed in this way. Covers invertebrates as well as vertebrate species. Would be a recommended or core text on Zoo Biology courses, BScs in Animal Science, and Animal Welfare MScs, as well as an invaluable practitioner reference. A lot of students interested in animal behaviour are interested in zoos. Each chapter covers species-specific content include the following information: Ecology and natural history as relevant to the zoo, behaviour and welfare measures based on ecological knowledge, feeding ecology and nutritional management, mating systems and reproductive characteristics, enrichment and behavioural diversity. The chapters are consistently formatted for ease of information, with end of chapter summaries, boxes with selected enrichment devices or welfare assessment methods for assessing welfare state, and directed reading of peer reviewed and other reputable sources that help advance care. A final Part explores welfare assessment tools, quality of life, veterinary interventions and evidence-based approaches. It looks at ways to increase the value of zoo and aquarium animals by enhancing visitor interest and visitor behaviour change. Also, research needs for keepers and how to build evidence into a daily routine, as well as management of native species programmes and the future of zoo research.

Egg Parasitoids in Agroecosystems with emphasis on Trichogramma was conceived to help in the promotion of biological control through egg parasitoids by providing both basic and applied information. The book has a series of chapters dedicated to the understanding of egg parasitoid taxonomy, development, nutrition and reproduction, host recognition and utilization, and their distribution and host associations. There are also several chapters focusing on the mass production and commercialization of egg parasitoids for biological control, addressing important issues such as parasitoid quality control, the risk assessment of egg parasitoids to non-target species, the use of egg parasitoids in integrated pest management programs and the impact of GMO on these natural enemies. Chapters provide an in depth analysis of the literature available, are richly illustrated, and propose future trends.

The population of the Persian leopard (Panthera pardus saxicolor) has drastically declined; this Asian leopard subspecies has disappeared from some parts of its former range. Containing large areas of potential habitats with leopard presence across almost all of its provinces, Iran is known to be the last stronghold for the Persian leopard in the region. This book comprehensively covers research, management and conservation practices of the Persian leopard, including: * The first phase of the Persian Leopard National Action Plan in Iran together with an innovative leopard insurance program and a contingent valuation practice with respect to the wildlife trafficking law enforcement in Iran * Research on a hypothesis about the risk of a major fragmentation and splitting the leopard distribution range in Iran into a northern and a southern parts * An innovative and empirically fitted species- and region-specific approach for assessing the cumulative effect of land use and land cover changes on the leopard persistence * Distribution modeling of leopard potential habitats on a regional basis, accompanied by ground validation techniques * An evaluation to three threshold rules to define the habitat suitability indices * Persian leopard habitats and relative corridors in the trans-boundary areas of the East Azarbaijan province of the northwest of Iran in the Caucasus Ecoregion. The innovative research and conservation approaches presented in this book will be of great interest to those studying the leopard and other large carnivore species. The innovative models presented in this book about cumulative effect of the land use and land cover changes will be beneficial to land use managers, planners and decision makers in selecting wildlife friendly solutions for development programs. The strategic and action planning model as well as the leopard compensation program as an insurance scheme are developed specifically for the local condition and leopard status in Iran.

Peatlands form important landscape elements in many parts of the world and play significant roles for biodiversity and global carbon balance. This new edition has been fully revised and updated, documenting the latest advances in areas such as microbial processes and relations between biological processes and hydrology. As well as thoroughly referencing the latest research, the authors expose a rich older literature where an immense repository of natural history has accumulated. The Biology of Peatlands starts with an overview of the main peatland types (marsh, swamp, fen, and bog), before examining the entire range of biota present (microbes, invertebrates, plants, and vertebrates), together with their specific adaptations to peatland habitats. Detailed coverage is devoted to the genus Sphagnum, the most important functional plant group in northern peatlands, although tropical and southern hemisphere peatlands are also covered. Throughout the book the interactions between organisms and environmental conditions (especially wetness, availability of oxygen, and pH) are emphasized, with chapters on the physical and chemical characteristics of peat, the role of peat as an archive of past vegetation and climate, and peatland succession and development. Several other key factors and processes are then examined, including hydrology and nutrient cycling. The fascinating peatland landforms in different parts of the world are described, together with theories on how they have developed. Human interactions with peatlands are considered in terms of management, conservation, and restoration. A final chapter, new to this edition, focuses on the role of peatlands as sources or sinks for the greenhouse gases carbon dioxide and methane, and the influences of climate change on peatlands. This timely and accessible text is suitable for students and researchers of peatland ecology, as well as providing an authoritative overview for professional ecologists and conservation biologists.

The indiscriminate use of chemical substances in industrial processes and anthropogenic activities, have resulted in the release of these compounds into aquatic ecosystems through municipal, hospital and industrial discharges, producing various undesired effects on the environment and on species of ecological interest. These compounds, such as metals, pesticides, emerging pollutants and other substances are persistent and susceptible to biotic and/or abiotic transformations, yielding metabolites that can be more toxic than the original compounds. In this book, researchers from diverse environmental science disciplines share their experiences in countries such as Argentina, Brazil, Colombia and Mexico, and critically examine the problem of contaminants in aquatic ecosystems in Latin America, as well as the risks presented by their presence.

Climate change is one of the most severe dangers for mankind worldwide. Beside the temperature increase, the sea level will rise and flood wide coastal areas, which is already remarkable today. The effects will be dramatic, in particular, at coasts with low elevation gradients such as at the German coasts of the North and Baltic Sea. The impact will be not only severe for coastal people, but still more for the unique coastal ecosystems, which harbors many plant and animal species that are already endangered today. This book focuses on the coastal terrestrial ecosystems of the German North and Baltic Sea. It describes the reactions of plants and animals (i.e. spiders, carabid beetles, bees and nematodes) on the future temperature and sea level increase. The combination of field and experimental studies is unique for Europe and for many parts of the world. It not only studies the actual elevation gradients and the climatic and saline gradients from West to East, but also the historical changes to document processes at coastal ecosystems that were already passed. In contrast to many books that studied the marine processes with similar backgrounds, this book concerns the terrestrial coastal ecosystems that were overall rarely studied and, in particular, never studied under this specific viewpoint.

Biology of Sharks and Their Relatives is an award-winning and groundbreaking exploration of the fundamental elements of the taxonomy, systematics, physiology, and ecology of sharks, skates, rays, and chimera. This edition presents current research as well as traditional models, to provide future researchers with solid historical foundations in shark research as well as presenting current trends from which to develop new frontiers in their own work. Traditional areas of study such as age and growth, reproduction, taxonomy and systematics, sensory biology, and ecology are updated with contemporary research that incorporates emerging techniques including molecular genetics, exploratory techniques in artificial insemination, and the rapidly expanding fields of satellite tracking, remote sensing, accelerometry, and imaging. With two new editors and 90 contributors from the US, UK, South Africa, Portugal, France, Canada, New Zealand, Australia, India, Palau, United Arab Emirates, Micronesia, Sweden, Argentina, Indonesia, Cameroon, and the Netherlands, this third edition is the most global and comprehensive yet. It adds six new chapters representing extensive studies of health, stress, disease and pathology, and social structure, and continues to explore elasmobranch ecological roles and interactions with their habitats. The book concludes with a comprehensive review of conservation policies, management, and strategies, as well as consideration of the potential effects of impending climate change. Presenting cohesive and integrated coverage of key topics and discussing technological advances used in modern shark research, this revised edition offers a well-rounded picture for students and researchers.

This book analyzes different facets of anuran amphibian distribution in South America. We integrate alternative biological metrics employing cutting-edge methods to understand the dynamic processes underlying species distribution patterns. By using the modern biogeographic toolbox, we explore how richness gradients, phylogenetic diversity, functional diversity, and range size/endemism distribution of amphibians vary along the continent. Moreover, we present a robust proposal for priority areas for conservation of anurans in South America that maximizes representativeness of distinct biodiversity facets.

David Quammen's book, The Song of the Dodo, is a brilliant, stirring work, breathtaking in its scope, far-reaching in its message -- a crucial book in precarious times, which radically alters the way in which we understand the natural world and our place in that world. It's also a book full of entertainment and wonders.

In The Song of the Dodo, we follow Quammen's keen intellect through the ideas, theories, and experiments of prominent naturalists of the last two centuries. We trail after him as he travels the world, tracking the subject of island biogeography, which encompasses nothing less than the study of the origin and extinction of all species. Why is this island idea so important? Because islands are where species most commonly go extinct -- and because, as Quammen points out, we live in an age when all of Earth's landscapes are being chopped into island-like fragments by human activity.

Through his eyes, we glimpse the nature of evolution and extinction, and in so doing come to understand the monumental diversity of our planet, and the importance of preserving its wild landscapes, animals, and plants. We also meet some fascinating human characters. By the book's end we are wiser, and more deeply concerned, but Quammen leaves us with a message of excitement and hope.

This book provides a scientific forecast of the development in aquaculture with a focus on the environmental, technological, social and economic constraints that need to be resolved to ensure sustainable development of the industry and allow the industry to be able to feed healthy seafood products to the future generations. The chapters included discuss the most critical bottlenecks of the development encompassing subjects of understanding the environmental impacts, the current state-of-art in monitoring programs and in coastal zone management, the important interactions between wild and cultured organisms including release of non-native species into the wild, the current trends within the development of aquafeeds along with human health aspects as well as the political, socio-economic and economic trends within the industry including a chapter on approaches taken by Non Governmental Organisations (NGOs) to aquaculture. Finally the last chapter provides different future scenarios of the industry based on the identified bottlenecks.

This book introduces ecologists to the wonderful world of modern tools for data analysis, especially multivariate analysis. For biologists with relatively little prior knowledge of statistics, it introduces a modern, advanced approach to data analysis in an intuitive and accessible way. The book begins by reviewing some core principles in statistics, and relates common methods to the linear model, a general framework for modeling data where the response is continuous. This is then extended to discrete data using generalized linear models, to designs with multiple sampling levels via mixed models, and to situations where there are multiple response variables via model-based approaches to multivariate analysis. Along the way there is an introduction to: important principles in model selection; adaptations of the model to handle non-linearity and cyclical variables; dependence due to structured correlation in time, space or phylogeny; and design-based techniques for inference that can relax some of the modelling assumptions. It concludes with a range of advanced topics in model-based multivariate analysis relevant to the modern ecologist, including fourth corner, latent variable and copula models. Examples span a variety of applications including environmental monitoring, species distribution modeling, global-scale surveys of plant traits, and small field experiments on biological controls. Math Boxes throughout the book explain some of the core ideas mathematically for readers who want to delve deeper, and R code is used throughout. Accompanying code, data, and solutions to exercises can be found in the ecostats R package on CRAN.

Until about 13,000 years ago, Europe and North America were home to a menagerie of massive mammals. Mammoths, camels, and lions walked the ground that has become our cities and streets. Then, just as the first humans reached the Americas, these Ice Age giants vanished forever. In Once and Future Giants, science writer Sharon Levy digs through the evidence surrounding Pleistocene large animal ("megafauna") extinction events worldwide, showing that understanding this history-and our part in it-is crucial for protecting the elephants, polar bears, and other great creatures at risk today. These surviving relatives of the Ice Age beasts now face an intensified replay of that great die-off, as our species usurps the planet's last wild places while driving a warming trend more extreme than any in mammalian history. Inspired by a passion for the lost Pleistocene giants, some scientists advocate bringing wolves back to Scotland, and elephants to America's Great Plains as stand-ins for their extinct native brethren. By reintroducing big browsers and carnivores to colder climes, they argue, we could rescue some of the planet's most endangered animals while restoring healthy prairie ecosystems. Critics, including biologists enmeshed in the struggle to restore native species see the proposal as a dangerous distraction from more realistic and legitimate conservation efforts. Deftly navigating competing theories and emerging evidence, Once and Future Giants examines the extent of human influence on megafauna extinctions past and present, and explores innovative conservation efforts around the globe. The key to modern-day conservation, Levy suggests, may lie fossilized right under our feet.

The human foot is a unique and defining characteristic of our anatomy. Most primates have grasping, prehensile feet, whereas the human foot stands out as a powerful non-grasping propulsive lever that is central to our evolution as adept bipedal walkers and runners and defines our lineage. Very few books have compiled and evaluated key research on the primate foot and provided a perspective on what we know and what we still need to know. This book serves as an essential companion to "The Evolution of the Primate Hand" volume, also in the Developments in Primatology series. This book includes chapters written by experts in the field of morphology and mechanics of the primate foot, the role of the foot in different aspects of primate locomotion (including but not limited to human bipedalism), the "hard evidence" of primate foot evolution including fossil foot bones and fossil footprints, and the relevance of our foot's evolutionary history to modern human foot pathology. This volume addresses three fundamental questions: (1) What makes the human foot so different from that of other primates? (2) How does the anatomy, biomechanics, and ecological context of the foot and foot use differ among primates and why? (3) how did foot anatomy and function change throughout primate and human evolution, and why is this evolutionary history relevant in clinical contexts today? This co-edited volume, which relies on the insights of leading scholars in primate foot anatomy and evolution provides for the first time a comprehensive review and scholarly discussion of the primate foot from multiple perspectives. It is accessible to readers at different levels of inquiry (e.g., undergraduate/graduate students, postdoctoral research, other scholars outside of biological anthropology). This volume provides an all-in-one resource for research on the comparative and functional morphology and evolution of the primate foot.
